Calculate duration from fixed date/time

Kratchie — Thu, 15 Dec 2022 11:41:58 GMT

Hi,

I've a column with fixed time which begins from 2000-01-01 00:00:00

If we find 2000-01-02 03:10:10 in that column it means 27h, 10 min, 10 sec in duration. How can I calculate and get it as result?

Have a great day

Hi,

Here is one way to do this:

Measure = var _mindate =CALCULATE(MIN('Table (2)'[Column1]),ALL('Table (2)'[Column1]))

var _h = DATEDIFF(_mindate,MAX('Table (2)'[Column1]),HOUR)

var _m = MINUTE(MAX('Table (2)'[Column1]))

var _s = SECOND(MAX('Table (2)'[Column1]))

return

_h & "h " & _m &"m " & _s &"s"

end result:

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!

Hi Kratchie

try to create a column with this:

Column = FORMAT([Duration]-DATE(2000,1,1),"HH:MM:SS")

i tried and it worked like this:

I assume you are later going to aggregate your durations in a measure, so please see this article for a good way to handle durations as decimals (in days) so you can easily do math and use them in visuals, but then display them as hh:mm, etc. when needed.

Hi ValtteriN,

When I created a new visual table and added only DURATION column with your script it worked like a charm. BUT when i'm adding more columns it stopped to work by any reason. Seems that only timestamps with seconds still works partly (only hours + seconds), but when it's whole hour. It doesnt work?!

Hi FreemanZ

Your script works perfectly with hours only. When it's more than 24 hours like 1 day + 6 hour it only shows 6:00

Hi ppm1,

This I have done before without any problem when it's two columns with both start/end date+time (split it into 4 columns (start&date, end&date, start&time, end&time) but now I need to get duration from fixed timestamps as I wrote above which isnt that easy. I have googled for different solutions but couldn't find any.

Kratchie hmm,

That seems quite weird. The first things that come to my mind are te following:

1. Are there some other dimension information or slicers affecting the visual?
2. Is the data format similar in both your example and the data in question

When I tried to re-create this the formula worked well even with whole hours and dates across different months:

hi Kratchie

not sure about your ultimate goal, try this:

Column =

VAR _d = TRUNC( [Duration]-DATE(2000,1,1))

VAR _hms = FORMAT((([Duration]-DATE(2000,1,1))-_d),"HH:MM:SS")

RETURN _d &" Days " &_hms

I tried and it worked like this:
